To all whom it may concern:

Be it known that I, NICHOLAS JOHN RUPP, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Greenhouse-Roof Oon` struction, of which the following is a specification.

This invention relates to improvements in roof constructions for greenhouses and has to do more particularly with a novel construction of that part of the roof, adjacent the ventilating sash, and a novel means of hinging the sash to the roof structure.

Heretofore, the ventilatingsash has been hinged directly to the header, supporting the upper end of the uppermostpane or panes of the roof glass, and as a result of this construction the uppermost panes of the roof glass have been frequently broken and cracked by reason of the strain imposed upon the header when the sash is opened and,

closed. Frequently the hinges of the ventilating sash become covered with ice and the working of the leaves and pins ofthe hinges is interfered with by paint and rust thereby necessitating the expenditure of considerable power in actuating the sash operating means. The strain imposed upon the header, when loosening the hinges at the pivots thereof, frequently displaces the header sufiiciently to crack the roof glass-andsometimes shift the header entirely out of place,

loosening its connection with the roof bars. This defective construction is entirely avoided by the improved construction embodying my invention, and in addition, my invention has for its Object the provision of a roof structure and ventilating sash wherein no shade is cast by the header and wherein the ventilatingsash discharges directly upon the roof glassV so that when the glazing pins sag, the resultant spaces between the header and the uppermost pane of roof glass, will not result in leakage.

A. further feature consists ina construction wherein the Ventilating'sash dischar es wholly upon the roof glass so as to effectua y prevent the freezing of water at the juncture of the sash and header and the resultant interference with the operation of the former.

Further objectsof my invention will be fully set forth in the accompanying drawing and will be more particularly pointed out and ascertained in and-by the appended claims.

In the drawing :-`-Figure l is a perspective with an intermediate roof bar.

view, partly in section, of a roof construction andV ventilator sash embodying the main featuresofmy invention. Fig. 2 is a sectional view on line 2 2 of Fig. l. Figs. 3, l and 5 are detail views of the form of hinge employed. j

Like numerals of reference designate similar parts throughout the different figures of the drawing.

As shown in the drawing 1 designates the ridge and 2 the roof bars, which abut the ridge and are inclined downwardly therefrom. The roof bars 2 are spaced apart fromeach other and are provided with the usual longitudinal shoulders 3 for receiving and supporting the roof glass 4 and the usual troughs or gutters 5 for receiving the water of condensation. A ventilating sash 6 is disposed upon the roof bars 2, at a point preferably adjacent the ridge 1, and in a manner to overlap the same as indicated in Fig. 1. The head member 7 of the sash lies adjacent and partly upon the ridge l and the base member 8 of the sash is disposed at a point remote from the ridge in a direction toward the eaves. The stiles 8 of the sash lie upon two of the roof bars and aline therewith while the sash bar 8 lies upon and alines The base member 8 of the sash is connected directly with one of the roof bars by a hinge 9, one of the leaves 10 being secured to a roof bar and the other leaf 11 being secured to the member 8. The stiles S are also hinged directly to the roof bars, preferably in a similar manner and by vsimilar hinges. rlhe preferred construction of hinge is shown in Figs. 3, Il and 5. The ventilator sash may be operated, by any of the well known devices commonly used for this Y purpose but as the operating mechanism forms no" .feature of this invention it is not herein shown or described.

The roof glass 4;, between those roof bars 2 whichare bridgedby the sash 6, terminates at and is supported'by headers 12 which eX- tendbetween and are supported at their ends on thel sidesof the roof'bars 2. Referring to Fig. 2 it will be seen that the' header 12 is disposed beneath the base member S of the sash so as to prevent the header lv12 from casting shade. Preferably the header 12 is reduced in thickness with respect to the width. of the base member 8 so that the latter, which is of normal size, overhangs the header 12 on both sides thereof. It will beseen from the foregoing construction that no shade will be cast Vand the header 12.

by the header 12, in addition to the shade the ventilator sash, in the use of nrvinvencast by the member 8, and that l thereby ention. A, further advantage results Iroin the tirely avoid the objectionable width. of parts heretofore necessary and which usually cast a width of shade greatly in excess of the coinbined width of the sash base and header.

By means of the foregoing construction it will be seen that water will overflow or drip from the margin 13 of the sash base 8 directly upon the roof glass 4 and that l thereby entirely avoid the objectionable freezing of water at the juncture of the sash base 8 and the header 12 and which has heretofore made it difh cult and sometimes impossible to open and close the ventilator sash. lt will also be seen that when the sash is open a space 14- is formed between the bottom of th sash base 8 and the top of the header 1.2 so that the water of condensation will run down the lower surface of the sash glass 15 until it reaches the front edge 16 of the sash base 8 wherefrom it will run down the lower surface 17 of said base and drip directly upon the roof glass 4 from the margin 18. By means of this construction l entirely avoid the necessity of providing a gutter on the front face of the header 12 and l also prevent the drippings of condensation from falling into the greenhouse.

In glazing a roof the panes of glass are laid from the eaves toward the ridge, in overlapping relation, and the last pane is usually out so as to fit between the next adjacent pane and the header. Each pane of glass is held .in place longitudinally by glazing pins 20, as shown in Fig. 2, and the weight imposed upon these pins causes them to in time and allow the panes to slide downwardly slightly. Furthermore, in cutting the uppermost panes, designated at 21, sufficient care is not always taken to sever the glass accurately at right angles to its lateral margins. From these two causes a great deal of dil'liculty has been experienced by reason of the consequent leakage caused by a lack of proper fit between the pane 21 By using my improved construction leakage will be impossible, at this point, because the sash base 8 overlaps the header 12 and discharges directly upon the roof glass 4 at a point beyond the header 12. Furthermore, the header is not subjectedr to any strain whatsoever and it would be impossible for the roof glass to be cracked or broken, as a result of operating l l i l l l l fact that the sash is hinged wholly to the roof bars, the mounting and strength of which is amply sullicient to withstand :in v strain resulting froin an iinperl'ectly operating hinge.

A great deal of diiliculty has heretofore been experienced by reason oi the warping of the sash stiles which dil'iiculty is wholl \v avoided, in my invention, b v hinging, or :1ttaching the hinges, directly to the stiles thereby preventing warping of either the sash base or the stiles` 1.
